Java 只能与主题一起使用的AppCompat小部件。AppCompat主题（或子代）

这里的iOS开发者被扔进了Android项目的狼群中。我收到了一些错误代码，这些代码都类似于meutils:View类androidx.appcompat.widget.AppCompatTextView是一个appcompat小部件，只能与Theme.appcompat主题（或子代）一起使用。只要运行以下代码段：

view = inflater.inflate(R.layout.f_basic_dashboard_screen, null, false)

我的充气机实例化如下：

val inflater: LayoutInflater = LayoutInflater.from(SqueaksApplication.getApplicationInstance())

squeksapplication.getApplicationInstance（）

只返回

公共类squeksapplication扩展应用程序的实例

对于这个问题，我找到的几乎每个答案都指向项目的清单作为问题，并且需要为项目提供一个主题。我的项目清单如下所示：

<application
  android:name=".SqueaksApplication"
  android:allowBackup="false"
  android:icon="@mipmap/ic_launcher"
  android:label="@string/app_name"
  android:supportsRtl="true"
  android:theme="@style/AppTheme"
  android:usesCleartextTraffic="true"
  tools:ignore="GoogleAppIndexingWarning,UnusedAttribute"
  tools:replace="android:icon,android:allowBackup">

您的问题是使用的

上下文：
val充气器：LayoutInflater=LayoutInflater.from（squeksapplication.getApplicationInstance（））

ApplicationContext
没有你的应用主题。

您需要传递的是
活动，而不是应用程序上下文。
发布styles.xml或themes.xml能否提供一个如何正确传递
活动的示例？@ZacharyBell您是否在活动或片段中膨胀视图？这是我所在的类
类DashboardScreensAdapter:RecyclerView.Adapter（），CoroutineScope{
它正在处理的类是一个
片段
它是
类仪表板屏幕片段：片段（），仪表板屏幕适配器。加载侦听器{
@ZacharyBell在片段中，例如，您可以使用requireContext（）。
